Elements and Performance Criteria

Context
Typical dials and indicators include (select relevant items):
analog dials:
pressure gauge
rev counter
temperature dial
digital readouts:
pH meter
temperature probe
ammeter
flow meter
weigh scales.

Calibration checks could include:
checking the date that the next calibration is required (e.g. weigh scale, pressure gauge)
using a calibration button on the instrument (e.g. zero button on an ammeter, calibration button on an electronic meter).

Resolution of equipment problems or non-conforming measurements/readings is restricted to responding in a routine, predetermined manner as specified in the procedures for your plant. All operations are performed to procedures.

Readings may need to be made at heights, in wet or restricted conditions, or close to hot or moving equipment.

Taking action may be reporting.

HSE
All operations to which this unit applies are subject to stringent health, safety and environment requirements, which may be imposed through State or Federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between performance criteria and HSE requirements, the HSE requirements take precedence.

Assessment context and methods
Assessment for this unit of competency will be on an operating plant. The unit will be assessed in as holistic a manner as is practical and may be integrated with the assessment of other relevant units of competency. Assessment will occur over a range of situations which will include disruptions to normal, smooth operation.

Simulation or case study/scenarios may be required to allow for timely assessment of parts of this competency unit (e.g. those parts of element 2 referring to out of range readings). Simulation should be based on the actual plant and will include walk-throughs of the relevant competency components. Simulations may also include the use of case studies/scenarios and role plays.

Critical aspects
Competence must be demonstrated in the ability to recognise situations requiring action and then in implementing appropriate corrective action. While it is not expected that the operator will understand the full implications of readings outside the normal range, there should be awareness of the safety implications and the appropriate priority for response for such readings.

Consistent performance should be demonstrated. In particular look to see that:
readings which are out of range or unusual/unexpected signs of problems or potential problems with the equipment/processes are recognised
appropriate action is taken in a timely manner
hazards are recognised and appropriate action is taken to control risks arising from such hazards.

These aspects may be best assessed using a range of scenarios/case studies/what ifs as the stimulus, with a walk-through forming part of the response. The assessment activities should include responding to a range of problems.

Resource implications
Assessment will require access to an operating plant over an extended period of time, or a suitable method of gathering evidence of operating ability over a range of situations. A bank of scenarios/case studies/what ifs will be required as will a bank of questions which will be used to probe the reasoning behind the observable actions.

Other assessment advice
In all plants it may be appropriate to assess this unit concurrently with relevant teamwork and communication units.

It may be appropriate to assess this unit concurrently with:
PMAOHS100B - Follow OHS procedures.

Essential knowledge
Demonstration of competence in this unit must include knowledge of the following:
basic units of measurement
measuring devices, including gauges, dip-sticks, thermometers and the like
graphs and scales
procedures related to this competency
typical problems with measuring equipment applicable to this competency
procedures for reporting or dealing with typical equipment problems and threats to safety.
